Which letter cluster will replace the question mark (?) to complete the given series?
ERKV, HYVK, ?, NMRO, QTCD
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. KFGZ
The logic used here is:
ERKV, HYVK, ? , NMRO, QTCD
Consider the first letter:
E + 3 = H, H + 3 = K, K + 3 = N, N + 3 = Q
Similarly, Consider the second letter:
R + 7 = Y, Y + 7 = F, F + 7 = M, M + 7 = T
Similarly,
K + 11 = V, V + 11 = G, G + 11 = R, R + 11 = C
Finally,
V + 15 = K, K + 15 = Z, Z + 15 = O, O + 15 = D
Hence, KFGZ is the correct answer.
